Prerequisite

• MeasurementSet

Etymology

From "MeasurementSet", "FIELD subtable" and "index".

Synopsis

This class provides lookup and indexing into an MS FIELD subtable. These services include returning rows numbers (which for the FIELD subtable are FIELD_ID's) associated with specific data in the subtable.

Example

Motivation

Collect together all subtable indexing and lookup for the FIELD subtable, for encapsulation and efficiency.
